Extremely disappointing. – Vigor SpO2 | Pulse Oximeter for Sleep Apnea, Asthma, and Blood Pressure Review

Whoever is selling this app should be extremely ashamed of themselves. Making money off people when you know your app doesn't work is not something to be proud of. Only giving it one star because I had to in order to review at all. -1,000,000 stars- and hoping this comes back to bite the creator.
